Probability is a numerical measure of the degree of uncertainty in various situations. It can have a positive value ranging from 0 to 1.
The words 'probably,' 'doubt, "most probably,' 'chances,' and so on all have ambiguous meanings.
Probability equals the number of times a favorable event occurs. the total number of outcomes
An outcome is the most likely outcome of a random experiment.
A random experiment has the possibility of producing various outcomes, which is known as sample space. It's represented by the letter S. When a coin flips, for example, the winner is determined by the head.
A sample point is a name given to each member of the sample space. For example, in a coin flip, the head is a sample point.
If the experiment's outcome is that E occurs in a sample space S, E is said to have happened. If the outcome is such that E did not happen, we say that E did not occur.
